Police say the parent, Annika McKenzie, 34, walked into the building without being cleared by security and waited in the hallway for her daughter’s math teacher, Catherine Engelhardt.
McKenzie believed Engelhardt had ‘put her hands’ on her 12-year-old daughter earlier in the day, according to ABC 7.

Engelhardt refused to speak with McKenzie, telling her to first get a security pass.

A fight then ensued.

Authorities say the teacher was shoved against the wall, placed in a headlock and thrown to the floor.

Several students also became involved in the attack, including McKenzie’s 14-year-old niece.

Another teacher was able to break up the melee and attend to Engelhardt.

She was unconscious for several minutes and rushed to Winthrop University Hospital.

Engelhardt, a mother and teacher of 20 years, has since been released and is recovering at home ‘in a lot of pain’, according to Newsday.

Speaking from her home to ABC 7, Engelhardt said she has long feared for her safety at the school.

‘It’s not like I thought a parent would do something, but I knew something violent was going to happen,’ she told the network.
‘I’ve warned (the school) time and again that the children have no respect for adults.
